It argues that the current software fault tolerance techniques are more accurately thought of as delayed debugging than as fault tolerance.

Systems are resourceful if they are able to determine whether they have achieved their goals or, if not, to develop and carry out alternate plans. Section 3 develops an approach to designing resourceful systems based upon a functionally rich architecture and an explicit goal orientation.},
